rIbis invention relates to new and useful improvements in mountings forbrake beam safety guards or supports, and the objects of the inventionare to provide ay mounting which is extended downwardly so as toposition the sai'ety bar supported` by said mounting below and in properrelationwith the brake beam, and to provide suitable Imeans arrangedtransversely in said mount-ing `and io bearing on top of said bar toprevent-theupd ward movement thereof.

Further objects of the invention areto provide a supporting bracketadapted to receive a brake beam safety bar or support and f resilientlysupporting the same, andmeans transversely disposed in saidbraclret andengaging thetop of said bar for limiting the upward movement of saidbar.

With these and other objects in view, my invention consists in certainnovel features of construction and arrangement of parts, -hereinai'termore fully described and claimed, and illustrated in the accompanyingdrawings, in whichm Figure 1 is a side elevational view of the safetybar showing the springplanl; and the mounting `tor said bar in crosssection.

Figure 10 shows another modified form of mounting.

Fig-ure 11 shows amounting provided with spacing projections riveted tothe side walls of the mounting. i

Figure 12 shows the spacing. projections formed integral with the wallsof the mount ing bent into engaging positions.

Figures 13 and 14 show a modiiied form of mounting wherein theside wallsthereof are provided with a series of apertures disposed in verticalplanes to properly space the safety bar.

Referring by numeralsto the accompanying drawings, 10 indicates thespring plank ci a car truck. 11 indicates atrussed brake beam comprisinga compression member 12, a tension member 11i, and astrut 15. A brakehead 16 is supported on each side of thebralre beam and A engaging eachbrake head is a hanger 17 which operatively. supports `the brake beam inposition. UnderlyingY each bralre beam is a safety bar or support18carried by amounting 19 which is secured to the unc erside of springplank 10, by suitable fasteningv devices 20. Mounting or bracketlQ ispreferablyiormed U-shape in cross section and is provided withhorizontally disposed side flanges 21 which are apertured to receive thefastening devices 20.

Atransverse pin 22 is centrally disposedin the lower portion ofmounting19 and is seated in apertures formed in the:sidewalls19a of saidmounting'. The edge of flange 18t of bar 18 is provided vwith a`downwardly opening recess or seat 24 which, when pin 22 is'placed inposition, is engaged by said pin, thereby locking bar 18 againstlongitudinal movement. The walls 19a are provided with aligned apertures25 which are disposed a suitable distancel above and to each sideofaperture-receiving pin 22.

A pin 26 is seated in each pair of aligned apertures 25 and bearson topof bar-18, thereby preventing upward movement of said bar andmaintaining it in interlocked relation `with pin 22. A resilient member27 is arranged in `bracket 19 and has its downwardly turned ends 28bearing against lips 29 which latter areformed b bending uawardl ortionsof the bottom wall `of bracket 19. The central portion of resilientmember 2'.7.is provided vvith a downwardly presented seatiBO which isadapted to be engaged by pin22, thereby distoring upwardly ysaidcentralportion of member 27 and increasing the tension of said member.rlhe upwardly curvedfportions 31 of member 27 bear against the undersideo1u the horizontally disposed iiange 18b of bar 18, thereby formingresilient connection between bracket 19 and said bar 18.

Portions 31 engage bar 18 atrpoints preferand said members form stops toprevent un- 'Y bar 18.

due upward movement of said'bar. `Members 25 are preferably formedsquare Vin cross sec-n tion as indicated at 25` innorderto providemaximum bearing ln the form shown in Figures 1fto y3, the

i' safety support or bar is resilientlysupported Y 1or eliminatesrattling, thereby'increasingthe lite inthe bracket or mounting and thisresilient support prevents vibration of the parts and of the fasteningdevices.

"In theiform shown in Figures 4 and 5, the barl 18 is rigidly supportedin mounting V32,

said Vbar resting on the bottom `wall oit saidV mounting and'is heldthereagainst by transverse members 34 which areseatedV in the side wallsot' mounting32and bear on top ot barrt.V f p Y 1n the Vpreceding forms,the transverse members25 'and 34 areshown as bolts being removable from'the brackets. ln the form shown in'Figure 6, transverse member 35 vis'shown in the'orm of afrivet being perma# nently ired'to mounting 36.A fA Y In theformshown in Figures 7 and 8, bar 18 is resiliently supportedin the mounting 37 by a resilient member 38 and is locked againstlongitudinal movement by a pin 39. Transl verse members`40 bear on topof bar 18 and y prevent it from moving in a vertical plane.

.These members consist ot' astrap, the ends of which are interposedbetween the horizontally 'disposed attaching flanges 37a of mounting 87Vand the under-side of spring plank 10 and are apertured forreceivingtheA fastening devices 41 Yby means of Which the mounting issecured-tothe spring plank. Thecentral portion of each strap40'is'depressed as indicated at 42 and extendsdovvnvvardly between thesidewalls ofl mounting 37 and bears yon top of bar 18 to act as stopslfor said bar.

The` form shown in Figure 9 shows bar18 rigidly supported in a bracketor mounting 44 and a transverse member 45 is attachedv to the sidevwalls of said bracket by' fastening devices, suchas rivets 46. v j f v l.In Figure V10 another modified form is l shown wherein bar 18 issupported in the mounting 47 and the latter is spaced from the springplank 10 by spacers 48 which are secured in position by Vrivets 49 whicharealso used inl attaching the inountin 0.

In the formshown in Figure 11 the bar 18 is spaced from the spring plank10 by projections or rivets 50 having enlarged heads 50a.

fr Said projections are fined to the side' Walls oit the mounting. Themodified form shown in Figure 12 discloses the side walls 51 of mounting52 provided withintegral lateral projections or lips 54 formed bycutting and bending inwardly portions of the walls 'i 1 l Figures 13 and14 show another.` modiiied l term wherein amounting 55 is formedV withlsurface for elgging Y `against.longitudinal movement'andsupportsextended side Walls 55? and the latter are provided withva plurality ofcentrally disposed it. A vertically disposed rovvjot apertures 58 1sarranged on each side ofv apertures V56 and.

locking the flatter against upward movement. Apertures 58 are arrangedin horizontal series, Veach otv` which is in al delinite correlationwith a corresponding aperture 56, Where'- by by insertingpin 5'? andpins59 in the respective apertures, bar'18 is locked in mount-V ing 55.Thus bar 18 may becarriedby said mounting in-one position close tothespring plank and in another spaced therefrom in case the brakebea-mishung low.
